Swift: Cannot assign to the result of the expression

Question

I am upgrading my Objective-C code to Swift. I want to update the frame based on the image size like below:

let imageViewFrame: CGRect = view.frame
if (image.size.width <= image.size.height) {
     imageViewFrame.origin.x = (view.frame.size.width - view.frame.size.height)/4
     imageViewFrame.size.width = view.frame.size.height
}

here I am getting an error saying: "Cannot assign to the result of the expression" what I should do to remove the error?

Thanks in Advance!

Answer 1

You're declaring imageViewFrame using let which makes it immutable.

You could use var instead of let for imageViewFrame which would make it mutable.

var imageViewFrame: CGRect = view.frame
